DURATECHDrain Bladder, Medium Drain Cleaning Bladder, Fits 1-1/2" to 3" Drain Pipes, Unclogs Stubborn Blockages in Kitchen Sinks, bathtubs, Showers, and Main drains

Worked great. Very easy, corrected the problem right away.

Unclogged the drain fast and easy

I attached it to my hose, turned the water on , and less than 2 minutes I heard a pop. Pulled the hose just to find the product had split in half. I was trying to unclog my steel downspout.

Haven't had to use this one yet but have used them with success in the past. Careful not to blow off the bladder down the drain

This product is amazing!! It really works!! Unclog my dish sink..

Chemicals and snakes didn't work. This did. Saved me hundreds on a plumber visit.

I have to clear my kitchen drain every year or so, likley due to too little of a slope in the drain plumbing, causing a build up of sludge, so the sink stops draining. I attach this to a garden hose from outside. remove the ptrap section to get a straight shot at the obstruction, insert this into the line and turn on the water. It seals up within a second and blows out the obstruction shortly therafter. Quick and simple, no chemicals.

Used for a 3" drain and the bladder burst apart after about 4 minutes of water pressure. Looks like Amazon will honor the return & refund. We eventually did get the drain clear using just a plunger and hose. I'd recommend you try that route before you buy something like this.
